Tried reducing the transitional part of the Boost VE by 5% ...didn't seem to help at all. It seems to me that I had a similar issue back when I first installed this engine/blower setup. I think it went away after I scaled the tune 50%.

It is still scaled down 50%. So I would have to scale it down further. Don't see where I am hitting any limits though.

Maybe DYNAIR[g/s] is exceeding the 512 g/s limit...
( Hmmm, I just looked in your log and it is not )
The problem is there are some tables you can't see here.... C6102 will only trigger p1514 and REP which is not your problem.... I would raise "neutral rev limiter to 7000rpms". and start there.

Raised fuel cutoff in P/N and disabled the ETC rev limiter altogether. Throttle did not close down.
Looking at frame 5908, it also appears that I will be close to 512 g/s shifting at 6500 RPM, even though the tune is already scaled down by 50%. I will gain a bit more room when Boost VE is adjusted to get the fuel mixture smoothed out.

I only changed B3330 to 7100 and set B2201 to "Disable". B3330 had no effect...didn't see how it would. B2201 is the one that makes a difference. But I would rather keep the ETC rev limiter if possible.
Seems that somehow the rev limiter is kicking in before 4000 RPM rather than the set value of 7000 RPM. Maybe it is the rate of RPM increase that triggers it?? Which appears to be around 7,500-10,000 RPM/sec when the issue occurs. The only other times the ETC rev limiter has kicked in was at 7000 on losing a driveshaft or transmission.
